The main protagonist of the story Nanami starts as a dirt-poor but otherwise normal high school student whose father runs out on her due to his gambling debts. Officials promply evicted Nanami from her home because the rent was overdue by several months. Shortly afterwards Nanami "saves" a strange man, Mikage, in the park from a dog. In gratitude he gives her his house and Nanami accepts due to having nowhere else to go and only later does she find out that Mikage's gift has a few strings attached.Although Nanami appears to be a weak human compared to her compatriots (Tomoe especially) her spirit is strong. Because of this Nanami tends to land herself in a lot of trouble without even trying. She also is kind, gentle, understanding and caring of those around her, even if they are "bad" people or Yokai. She is also something of a busybody, a bit of a tomboy and has a real bad habit of promising things without thinking said things through.
The Chick: She is the only female at Mikage shrine and she tends to do more bickering with Tomoe than doing godly duties.
Chronic Hero Syndrome: Pretty much her defining character trait. She will do whatever she can to help those she cares for and those in need; no matter if she just met the person or how impossible the situation might seem.
Clingy Jealous Girl: Not immediately apparent but she gets angry when Tomoe flirts with other girls.
Expy: Just as Tomoe shares many similarities with InuYasha, Nanami has more than a few things in common with Kagome.
Fish Out of Temporal Water: Mizuki has an artifact that can send people back in time. Of course, Nanami winds up using it and she sticks out like a sore thumb in the past.
Friendless Background: We get to see bits and pieces of her back story and why this is. To give one example, she responds to her classmates in elementary school asking what will Santa bring by saying she doesn't know who this Santa is but he's not getting into her house because she made sure it was locked up good and tight. Of course, this changes eventually.
Girlish Pigtails: As a child Nanami had her hair up in short pig tails but now, as noted by Tomoe, she hardly ever puts her hair up.
The Heart: Likes playing match-maker, steers Tomoe to the path of heroism instead of jerkism, forgives Mizuki for the Shotgun Wedding attempt and allows him to come to the shrine so he won't be alone anymore.
It's All My Fault: After she fails to purify the youkei residue and Ami gets hurt and again when Jirou sacrifices himself for her.
Interspecies Romance: Nanami is one out of the three people (the other two are Mikage and Kayako) in the series that truly believes that Humans and Yokai can get along and love each other. She becomes infatuated with Tomoe fairly quickly but it takes awhile for Tomoe to start returning her feelings and even longer to admit it.
Not So Different: Tomoe and Nanami share a few similarities. They both have lost a loved one that they deeply cared about (Nanami lost her mom and Tomoe lost Yukiji); both were abandoned by someone (Tomoe by Mikage and Nanami by her dad); both have bad tempers (though Tomoe's is on a shorter fuse than Nanami's); both speak their mind no matter what the situation is; both have a rebellious streak and don't behave like society expects them to.
Tsundere: Of the Type B variety. Usually very sweet and kind, but when Tomoe is in Jerkass mode, she can get quite violent with him.
What Beautiful Eyes: In the recent manga arcs her vivid eyes get remarked and commented on their beauty by other charcters. In fact Tomoe says that he fell in love with "Yukiji"(Nanami) because of the look of her eyes.
The deuteragonist of the series; Tomoe is a powerful Kitsune that has been around for a few centuries. Tomoe's life before coming to Mikage shrine was violent and bloody and he spent his days carving a path of death and destruction across the human and yokai world before meeting Mikage. He eventually became Mikage's familiar and served in that position for several centuries before Mikage left the shrine twenty years prior to the beginning of the story. He later serves as Nanami's familiar (unwillingly).Tomoe bears many of the traits one might expect from a fox yokai; he is handsome, cunning, sly and possessed of a certain allure that those he meets often find difficult to resist. Personality wise he is something of a Jerk Ass and a Deadpan Snarker. Despite this he does show a softer, caring side on a few occasions. Tomoe also displays unusually strong sense of loyalty and honor on several occasions; such as standing watch over Mikage's crumbling shrine for twenty lonely years and going above and beyond the call of duty as Nanami's familar.
Battle Butler: Before Mizuki came along Tomoe did just about all the chores in the shrine, from cutting the grass to cooking Nanami's meals to doing the laundry. Even after Mizuki takes on some of the workload Tomoe still does quite a few chores.
Beleaguered Assistant: Let's face it, Nanami's tendency to act on impulse has made his life difficult on more than one occasion.
Berserk Button: Hurt or threaten Nanami and you're in for a world of pain.
Brutal Honesty: Especially towards Nanami but he will tell just about anybody what he really thinks about the situation whither they asked him to or not and he will usually do it in the rudest possible way.
Chick Magnet: Has a lot of female admirers in universe; both as a demon and disguised as a human.
Gender Bender: He winds up posing as Nanami three times. The first when she was sick, he covered for her at school. The second time when she was attending the conference, he also covered for her at school. The third time, well...
Little Bit Beastly: Has claws, fangs, fox ears and tail but other wise looks like a young man in his twenties.
The Loins Sleep Tonight: He heads to the Red Light District the moment Nanami leaves the shrine for a few days. Doesn't really do anything though and it is implied he mainly went there because he was feeling lonely.
Long-Haired Pretty Boy: Normally has a short pageboy haircut but in flashbacks is shown to have long hair and one time Nanami does see him with long hair it triggers a nose-bleed.
Only Sane Man: He is a lot more grounded, pragmatic and realistic than either Nanami or Mizuki. He also engaged in Pragmatic Villainy when he hung out with Akura-ou as opposed to his partner's senseless killing sprees.
Perpetual Frowner: Tomoe actually has a lot to be pissed about-Mikage abandoning him for starters-and he manages to be pissed at just about anything and everything.
Power Makes Your Hair Grow: When the power limiter Mikage placed on him is removed his hair grows from a short pageboy style hair cut to being draped over his shoulders and going down most of his back.
Power Limiter: As a familiar his Yokai powers seem to be weakened due to his bond to the shrine.
Princely Young Man: Definitely looks young and as Akura-Ou points out Tomoe had/has an elegant, prince-like feeling to him.
Semi-Retired Monster: His time with Mikage seems to have tempered some of his more extreme tendencies since before meeting him Tomoe did not mind killing and was quicker to resort to violence. His current moral outlook is somewhat contradictory; on one hand he still feels little patience for the weakness and frailty of creatures less powerful than himself. At the same time, however, he has grown gentler and more thoughtful and tends placing greater value on all forms of life and humanity in particular. Still he doesn't seem to regret his past and sometimes dreams of going back to the "good old days."
Sugar and Ice Personality: Normally he is rude, self-centered, confrontational and a general all-round Jerk Ass. But there are times when he shows that he can be kind and even down-right sweet when he wants to.
The Tease: Behaves like this towards Nanami once. She is not pleased.
Trademark Favorite Food: Tomoe's favorite food is sasamochi. Ironically, he came to like it because originally Nanami fed it to him when he was injured in the past although he had no recollection of the event in the present.
White Hair, Black Heart: Well, it was more of White Hair, Dark Gray Heart to begin with but by the time the story starts he has mellowed out a bit, though he still acts like an asshole.
Kotetsu and Onikiri
Two spirits who belong to the Mikage shrine. They are extremely optimistic and supportive of Nanami being the new Land God and have helped Nanami in many complicated situations. They also rely on and respect Tomoe very much, addressing him with the honorific -dono which roughly means 'master' or 'milord'. They always wear masks and what their true faces are is a mystery.
Mr. Exposition: Their main purpose in the storyline, besides comic relief, is to supply information to Nanami, other characters and the audience. For example, they are the ones who informed Nanami both about the familiar contracts and how to create them along with the talismans. They also told Mizuki, and by extension the audience, about how Tomoe became Mikage's familiar in the anime.
Nightmare Face: Implied in the anime, which features a flashback scene were Tomoe asks why they wear those masks. He promptly lifts one up, immediately looks kind of sick and disturbed and then puts the mask back down without saying a word.
Mizuki is a snake familiar of a Water God and like Kurama briefly serves as an antagonist before being put in his place by Tomoe. He fell in love with Nanami when she saves his life from her cruel classmates by releasing him out the window while in snake form. He starts off as being eerie, even bordering on creepy, but is eventually shown to be just lonely and more than a little bit naive. Eventually, he becomes Nanami's familiar, which pisses Tomoe off big time.
Crazy Jealous Guy: Mizuki has quite a bit of jealousy towards Tomoe and he is often seen trying to get Nanami to hate Tomoe by telling her lies and half-truths about him. Like the first time he used his little time travel incense burner.
Mizuki: "...the wonderful feeling of being dominated by the god...so irresistible! Please, say it again, Nanami-chan! Bind me with the invisible chain!"
Humans Through Alien Eyes: Mizuki knows next to nothing about human culture or dealing directly with humans on a regular basis. Just witness his little trip into Tokyo.
Insistent Terminology: Refers to himself as Divine Beast as opposed to a Yokai. Tomoe ends up screaming at him That's the same thing, Idiot!
I Want My Beloved to Be Happy: Very obviously has a crush on Nanami and is a rival to Tomoe for her affection and attention. Still, he helps Nanami save Tomoe on more than one occasion simply because Nanami cares about Tomoe.
Non-Action Guy: Mizuki seems to be stronger than any human and has quite a few magical tricks up his sleeve but so far he hasn't shown any fighting skill, despite being a familiar.
Not So Different: Like Tomoe Mizuki was waiting for a god that would never come back. Then there is love for and loyalty to Nanami they both share. And even though he usually acts all nice and innocent, Mizuki can be just as much of a Jerk Ass as Tomoe when he wants to.
Shotgun Wedding: Tries to do this to Nanami which wasn't exactly the smartest thing he has ever done.
Skilled, but Naive: Mizuki knows quite a bit about magic and the supernatural and divine subjects. Knows next to nothing about human society and has trouble even interacting with other people.
The Rival: Tries to outdo Tomoe as being Nanami's most useful familiar.
Vitriolic Best Buds: Despite everything he seems to view Tomoe as a friend and even kindred spirit considering how he and Tomoe both lost their masters.
The former land god of Mikage Shrine. Twenty years prior to the beginning of the story, he mysteriously vanished from his shrine. Upon returning to his home town, he was chased up a tree by a dog and was rescued by Nanami Momozono. As a thanks, Mikage bestowed his home and mark to Nanami through a kiss to the forehead. He is often seen helping Nanami when she loses faith in herself or when she is confused or scared what to do as the Land God, but only when Tomoe is not around.
Disproportionate Reward: To Nanami. Running off a not-so-threatening and a not-so-big dog doesn't usually warrant godhood. Turns out that it isn't. The real reason he rewarded her is because Nanami created a Stable Time Loop and told a past version of him her life story, setting that plot in motion.
Team Dad: Once he came back he started acting as the father figure for the whole shrine. Right down to the part of making Nanami focus on her school work and scolding Tomoe when he acted inappropriately.
Weaksauce Weakness: Mikage is stated and shown to have a deep fear of dogs. Somewhat ironically he picked Tomoe as his familiar even though he was a Kitsune (the fox is a relative of the dog family.)
Yonomori Mitsuha is a water god whose shrine was built by the people of a village that feared that the reason a near river often washed away children was beacause of a curse. However, as a god born to met the needs of the people in her village, she disappeared when the people of her village left. She was Mizuki's goddes. When Nanami travels to the past she meets a younger Mitsuha and they become friends.
She is the goddess of thunder and lightning. She is known to take a sadistic delight in abusing her familiars and she goes through new sets of them at an unheard of rate (this even earns her an in-series nickname). When she learns that Nanami is Tomoe's new master, she thinks that her chance has finally come to make him her familiar.
Vain Sorceress: Narukami is a goddess but otherwise she fits this stereotype perfectly.
The god of war. He looks down on Nanami for being a weak human. An attitude that latter cause him to get his ass handed to him by Tomoe. Than we latter find out he is the reason Tomoe was lying wounded on the riverbank at the start of Yukiji romance arc.
A Wind God who is more than a little effeminate. He was assigned to give the God's Summit Invitation test to Nanami and Kayako by Ookuninushi and was also in on the fact that the test results were already preplanned for Nanami to win. Otohiko is sometimes casual and can sometimes be a little insulting or melodramatic in his manner of speaking. When speaking with, spoken to by, or simply being in Ookuninushi's presence, Otohiko acts very girly. Otohiko is good friends with Mikage, who in turn also sees him as a close friend. They are often seen together in the anime, and in the manga it was also strongly hinted that they were close friends.
Bunny-Ears Lawyer: His Ambiguously Gay mannerisms and other personality quirks aside, Otohiko is very good at what he does. Still, even his best friend, Mikage, says he can't believe Otohiko is a diety sometimes.
The God of Wealth, Ookuninushi is a famous god amongst the gods. He is very dramatic, flashy and tends to overreact but is rather charming. He was first mentioned in Chapter 9 where he had lent Narukami his Lucky Mallet. The Yearly God's Summit was held in his shrine and he was the one who arranged the test to go to the God's Summit between the two human gods Nanami and Kayako. Ookuninushi had actually invited Nanami so she could guard Yomotsuhira, the Yomi-no-kuni's boundary.
An innocent girl who is Nanami's classmate Ami is the first friend that Nanami made at her new school. Originially, Ami thought Nanami to be a little strange because of the strange occurrences that constantly happened around her. After Tomoe, who was disguised as Nanami, saved Ami from a demon she began to hang around with Nanami and became her official friend when Nanami helped her talk with Kurama, whom Ami had a crush on at the time. She appears to have some form of extrasensory sense when it comes to spiritual matters and she thinks that Nanami is a miko.
Loving Bully: A classmate asks him if he is this but he denies it.
A "living god" from Kyoto, Kayako hails from the famous Hiiragi family which is said to have produced powerful psychics for many generations. She has many followers and in the public eye she is shown to be quite calm and cool, but in private, she is quick-tempered and arrogant. She does, however, show that she can be wise, understanding and even nice when she wants to. She comes to Nanami's school as an exchange student and becomes her rival in the contest to see who is more suitable to go to the god summit.
Not So Different: She is one of the few people that believes humans can love Yokai besides Nanami. Also, she just wants to be a normal teenage girl much like Nanami.
Her witchy attitude towards Nanami is all the more aggravating when one recalls that Nanami actually is a land god, while Kayako is completely human, albeit with psychic/spiritual abilities. Which one of them is a "wanna-be god" again?
Outof Focus: Disappears from the story after her arc is resolved.
A beautiful peasant girl from the past, who knew Tomoe and was his lover. Or so we think at first. She was adopted into a noble family after her original village was destroyed by youkai with some non too subtle hints that Tomoe had a part in it.
Voiced by: Suzuko Mimori (Japanese), Tia Ballard (English)
Break the Cutie: Let's see, her village gets destroyed by demons, losing her home, her family and friends. She get's adopted and marries into money, still she develops good relations with her adoptive family and her husband's, after some years she finally gets pregnant... Only for that family to be wiped out by Akura-Ou. And though she hates demons with a passion she ends up becoming dependent on Tomoe, as she needs his help to stay alive and give birth to her child.
Cool Big Sis: To Nanami and Fuuta, with a bit of "cool mother" mixed in.
Doomed Hometown: With hints that Tomoe might have been involved in the destruction.
Fantastic Racism: When she first encounters Nanami she hates youkai to the point her response to hearing the village militia is hunting down a wounded Tomoe is to throw a little party.
Happily Adopted: After the destruction of her home village, a rich merchant adopts her. She seems to be quite happy with this.
I Want My Beloved to Be Happy: After being married for many years and not being able to get pregnant, even though she loves him, she asks her husband to search for a younger wife/concubine who would be able to give him heirs.
But he answers her that why would he look for another wife when he has her... And they both love each other a lot!.
Rags to Riches: Used to be an ordinary peasant girl but is eventually adopted into a well off family.
So Beautiful, It's a Curse: She is a gorgeous young woman, but it brings her more trouble than anything... Unwanted male attention, youkai and human alike.
Strong Family Resemblance: Nanami is mentioned to look a lot like Yukiji, and Yukiji keeps recalling the warmth of her birth-family whenever she is with Nanami. The reason is that Nanami is her descendant.
One of the main supporting characters Kotarou is a 18 year old boy first introduced Himemiko requested Nanami to help her to find him because of she had a crush on him. Kotarou was shy around Himemiko when he first met her and because of his low self-esteem he doubts at first that Himemiko actually loves him and that it might just be a cruel prank of some kind. After getting to know her, he grew fond of her and eventually fell in love with her. He also forms a friendship with Nanami and Sukuna.
Voiced by:Ryōhei Kimura (Japanese), Chris Burnett (English), Miguel Angel Ruiz (Latin American Spanish)
Adorkable: Yep. It's part of the reason Himemiko falls for him.
Butt Monkey: Implied to be in-universe. Why else would he think Himemiko having a crush on him might just be a cruel prank?
Cry Cute: The reason Himemiko fell for him when he was a child.
Sukeroku, also known as Suke, is an inhabitant and guard for Yukiji's village. He seems to have a lot of respect for Yukiji, despite the other villagers, especially the other local guards, feeling the opposite. He is very cheerful and thoughtful, a bit childish and is seen to have a liking for sake. However, he is apparently clumsy, complains a lot and gets tired fast.
Fuuta is Yukiji's servant. He admires Yukiji and wishes for her happiness due to her hard life after the destruction of her village, fully supporting her decision to marry. However, due to this regard for Yukiji, he gets mad very easily when people insult her. He also seems to see her as a mother-like figure. He also treats Nanami as a big sister, calling her by name without a title.
Big Brother Instinct: To "Himetarou" who is Tomoe disguising himself as child so he could escape and heal his injuries.
Kurama's brother, Jirou is currently the fourth chief of Kurama Mountain; leading all other tengu due to his unsurpassed strength and speed. Jirou is initially portrayed as a cruel leader. He is shown to be merciless and banished many other tengu when they showed any sign of weakness.
That Didn't Happen: Does this immediately after he asks Nanami if she will stay on Kurama Mountain.
A wildly popular music idol with the gimmick of being a "fallen angel", with goth makeup and a bad boy attitude. He serves very, very briefly as an antagonist in the series before Tomoe puts him in his place. Eventually becomes a friend of Nanami's and a rival for her affection to Tomoe. Personality wise, Kurama is very charismatic and due to his popularity, very arrogant and selfish as well.
Voiced by:Daisuke Kishio (Japanese), Sean O'Connor (English), Jose Gilberto Vilchis (Latin American Spanish)
All the Other Reindeer: Was an outcast because he hadn't mastered flying at the appropriate age and he got special treatment for being the chief's son.
Bishounen: There is a reason all the teenage girls in the series and even some of the boys like him.
Jerk with a Heart of Gold: The first time Nanami meets him he acts like a regular asshole. He mellows out a little afterwards but he still has his moments.
Lady Killer In Love: He starts to fall for Nanami following, and partly because of, the ostrich incident.
Money to Throw Away: He slips a considerable amount of money into Nanami's pocket in his introduction story but to him is pocket change.
Most Definitely Not A Demon: He's terrified of the idea that his fans will find out what he really is and when Tomoe and Mizuki spill the beans to one of Nanami's classmates his denial left something to be desired.
Suirou is much beloved by the tengu in the Kurama Mountain and even Kurama argues that Suirou would be a much better chief than Jirou. He took care of Kurama during his childhood and was the first to show him affection. He was also the most skilled at flying among the tengu until he lost his wings while protecting Kurama. The tengu also consider him to be very beautiful, more beautiful even than Nanami.
She is the princess of the swamp Tatara and a catfish spirit. Used to be friends with Mikage. She approaches Nanami because she wants to find the human boy Kotarou again, with whom she fell in love with 10 years ago. She and Nanami become close friends.
The Dragon King (Ryuuou) of the Seven Seas, Sukuna is a proud man who always loves a good fight. This guy has a been waiting to seek revenge against Tomoe for 526 years for ripping out his right eye and attacking the north gate of his castle. Though aggressive and temperamental, he is afraid of his wife's anger. She disapproves of his fights, saying they mar his beautiful face. He is forced to give up his grudge against Tomoe after she befriends Nanami.
Hot-Blooded: Aggressive? Check. Temperamental? Check. Burningly passionate about everything that he does? Double Check!
Jerk with a Heart of Gold: His hot-blooded nature does result in him picking fights, callously ignoring his wife's desires, and being fairly insulting in general. That said, he makes an effort to help out people he sees in trouble - he makes sure to save Nanami from drowning despite not even knowing her at the time, for example.
Also referred to as the Evil King, Akura-Ou is a brutal and sadistic demon and the current Big Bad of the series and someone who very much enjoys killing. He consistently shown to be arrogant, violent and confident in his powers along with quick-tempered and somewhat of a brat that is used to getting his way. Six hundred years ago he wrecked havoc to the world of both yokai and humans alike with Tomoe at his side. He and his partner were so powerful that not even the gods of Izumo could defeat them. But then Tomoe fell in love with a human woman, which broke up the alliance. After being captured by the gods he was sent to Yomi-no-Kuni and split, his soul sealed into a group of rocks whilst his immortal body thrown into eternal fiery flames. A few centuries later a young, recently-deceased boy named Mori Kirihito came to him and asked him to send an 'I'm sorry' message to his parents because they had fought just before his death. Akura-Ou accepted out of boredom and curiosity and hence possessed Kirihito's body, waking in a hospital room and being hugged by 'his' mother.
And I Must Scream: Let's see, his soul was ripped from his body and sealed in a cavern with no light, no outside contact for centuries while his body was tossed in a lake of fire. Yeah, I would say that qualifies.
Monster Sob Story: He's indubitably evil, but it's hard not to feel at least a tiny twinge of empathy for him during his flashback to his first incarceration in Yomi-no-Kuni, his reaction to "awakening" in the world of the living, and his reaction to Nanami's finding him during his second incarceration.
Prince of Inunaki Swamp. Beautiful, rich and arrogant; Nishiki is every bit the spoiled, pompous aristocrat. Already at this young age was he betrothed to Himemiko in order to unite their kingdoms and have control over Tatara Swamp. He's Himemiko's fiancee.
Character Development: He is first portrayed as a pompous ,arrogant man who thinks of nothing but himself and fully trusted his advisor, Shiranui, to handle all his affairs. After he meets Nanami he learns to apologize, think for himself, love and let go.
A mysterious youkai who wishes to help Akura-Ou. He promises to take over Kurama mountain to show his strength. Originally, he was known as "Furball," because, well, he resembled a furball. Back then he was constantly ignored and ridiculed for his looks and body odor. He attempted to gain strength to impress Akura-Ou and when then that didn't work he killed Suke and took over his body.
Butt Monkey: Five hundred years ago he was, his present day version still is too some degree.
The Chessmaster: His scheme to take over Kurama mountain definitely shows aspects of this.
